Documentary filmmaker Margaret Brown was born and raised in Mobile, Ala., and has had an absorbing interest in the American South, including her 2004 documentary \u201cBe Here to Love Me: A Film About Townes Van Zandt.\u201d But only while filming \u201cThe Order of Myths,\u201d in 2008, she learned of the last known slave ship brought to the United States in the late 1850s, and the nearby community former slaves formed. \u201cI didn't remember learning about that in school. That was the first time I had heard of the Clotilda [ship] or Africatown,\u201d she states.\xa0That was the moment when she came across the topic of her newest project, the film \u201cDescendant.\u201d Now, Brown shares how she created partnerships to make the film, and got Questlove, Netflix and the Obamas to become involved in it.\xa0But first, Kim Masters banters with Matt Belloni about Warner Bros. Discovery\u2019s unpredictable decision to hire filmmaker James Gunn and producer Peter Safran to run the DC Universe.\xa0
